Documents Test Institute No. Documents Document-No. Date [T1] Audit Report Test Laboratory Rockwell Shanghai [T2] Validation Test Results, 800H and 800T 3.3. Test samples Validation_Results H_T_ 25_11_2009.xls No test samples were required for the inspection. The inspection was executed based on the information and documents provided by the manufacturer Previous test reports [R1] Report about the inspection of test reports for the determination of B10d values for emergency switches of families, 800H and 800T of Rockwell Automation Report-No.: 968/EL /10 dated Tests and test results 4.1. General The measuring and test equipment, which has been used by the TÜV Rheinland Group in the tests described in the following, is subject to regular inspection and calibration. Only devices with valid calibration have been used. The devices used in the various tests are recorded in the inspector s documentation. All considerations concerning uncertainty of the measurements, so far applicable, are stated in the inspector s documentation, too. In cases where tests have been executed in an external test lab or in the test lab of the manufacturer and where the results of these tests have been used within the here documented approval, this has occurred after a positive assessment of the external test lab and the achieved test results in detail according to the Quality Management procedure QMA Testing according to IEC The manufacturer has provided proof that the emergency stop switches have been tested according to the applicable product standard IEC in the past. The switch families 800H and 800T have been tested with positive results by the Test Institute DEMKO, see [D6]. The variants of the switch family have been tested with positive results by Rockwell Automation, see [] and [D8] Testing for the determination of B 10d values Rockwell Automation has defined a test method and a number of test set-ups for the BB10d testing of the different variants of the emergency stop switch families, see [D2]. The test method and test set-ups have been agreed with the Test Institute based on the applicable requirements of the standards listed in chapter 2. The test method and test set-ups are judged to be suitable for the B 10d testing. Further Rockwell Automation has defined failure criteria and methods for the evaluation of the test results from the B 10d testing, see [D2]. The failure criteria and methods for the evaluation have been agreed with the Test Institute. Report-No.: 968/EL /10 Page 3 of 5

4 The defined failure criteria and methods for the evaluation of the B 10d test results are judged to be suitable for the determination of B 10d values for the devices under test in accordance with the applicable requirements of the standards listed in chapter 2. The testing for the determination of B 10d values has been performed at the Rockwell Shanghai Laboratory. The laboratory has been inspected by the Test Institute, see [T1]. It was found that the laboratory is organised according to the requirements defined in ISO/IEC and that the laboratory is capable of performing the testing for the determination of B 10d values. The detailed test results from the testing for the determination of B 10d values are documented in [D3], [D4] and [D5]. The manufacturer performed a re-testing for the 800T family of switches with a higher number of test samples, see [D10]. The inspection of the test reports showed that the testing has been performed properly in accordance with the applicable requirements of the standards listed in chapter 2. The test reports are accepted by the Test Institute Cross reference for family The family of switches is additionally sold under the brand name. Rockwell Automation has provided a cross reference list [D9] which shows the relation between the devices of the and families. As these devices are technically identical it is possible to transfer the results from the testing of the family switches to the family switches Results of the determination of B 10d values Based on the documented test results, see [D3], [D4], [D5] and [D10], the Test Institute has made calculations in order to determine the resulting B 10d values for the devices under test, see [T2]. The results from these calculations have been compared to the calculation results derived by Rockwell Automation as documented in the test reports. No significant deviations have been found. The following table lists the resulting B 10d values for the different variants of the emergency stop switch families, 800H, 800T and. The B 10d values have been determined with a confidence level of 90 %. During the B 10d testing an electrical load of 20 ma provided by a 24 VDC power source was used.

Summary The inspection of the test reports for the determination of B 10d values of Rockwell Automation for the emergency stop families, 800H, 800T and came to the conclusion that the testing has been performed properly in accordance with the applicable requirements of the standards listed in chapter 2. Further the evaluation of the test results in order to determine B 10d values has also been performed in accordance with the standards listed in chapter 2. The B 10d values listed in chapter 4.5 can therefore be used as B 10d values for the emergency stop devices of families, 800H, 800T and.
